Abstract

This experimental studies were performed in order to prove the effect of Phospholipase A₂(PLA₂) Herbal-acupuncture by using rats that had neuronal damage due to the Middle Cerebral Artery Occulsion(MCAO). We observed the change of extracellular concentrations(μM) Of dopamine, DOPAC, HVA, HIAA, glutamate, aspartate, GABA, glysine, taurine, alanine, and tyrosine as extracted by vivo microdialysis, in the PLA₂ Herbal-acupuncture administrated rats(240-260g, Sprague-Dawley) subjected to the MCAO. The dialysates were extracted three times before the MCAO and six times after the MCAO every 20 minutes, and ana lysed by highperformance liquid chromatography(HPLC). PLA₂ Herbal-acupuncture significantly inhibited glutamate and tyrosine which are stimulant neurotransmitters at brain ischemia, and it significantly decreased glycine, GABA, taurine, and alanine which are inhibitory neurotransmitters at brain ischemia. PLA₂ Herbal-acupuncture may prevent delayed neuronal death(DND) in selectively vulnerable focal areas of the brain effectively.
